Martin Kaste

Martin Kaste is a correspondent on NPR's National desk. He covers law enforcement and privacy, as well as news from the Pacific Northwest.

In addition to general assignment reporting in the U.S., Kaste has contributed to NPR News coverage of major world events, including the 2010 earthquake in Haiti and the 2011 uprising in Libya.

Kaste has reported on the government's warrant-less wiretapping practices as well as the data-collection and analysis that go on behind the scenes in social media and other new media. His privacy reporting was cited in the U.S. Supreme Court's 2012 United States v. Jones ruling concerning GPS tracking.

Before moving to the West Coast, Kaste spent five years as NPR's reporter in South America. He covered the drug wars in Colombia, the financial meltdown in Argentina, the rise of Brazilian president Luiz Inacio "Lula" da Silva, Venezuela's Hugo Chavez, and the fall of Haiti's president Jean Bertrand Aristide. Throughout this assignment, Kaste covered the overthrow of five presidents in five years.

Prior to joining NPR in 2000, Kaste was a political reporter for Minnesota Public Radio in St. Paul for seven years.

The surprise announcement of criminal charges in Baltimore Friday morning definitely got the attention of police officers. The decision has been welcomed by protesters, but it's causing dismay for law enforcement across the country.

Bob Ball is a real estate investor in Portland, Ore., but that's just his day job. For the past 20 years, he has also been a volunteer cop.

"When I was new, it was the best time of my life. I got to go out there and wear a white hat and help people and make a difference in my community, one little piece at a time," Ball says. "That's a very, very fulfilling thing to do."

This is real police work. On one occasion, Ball had to pull his gun on a guy threatening a woman with a knife.

When James Craig was a young man in the 1970s, he says law-abiding people wouldn't dream of carrying guns. But then he left town to pursue a career in policing. In the years he was gone, Michigan liberalized its gun laws, making it easier for people to get concealed-carry permits.

When he came back to become Detroit's police chief in 2013, he found a whole new reality.

"You would have thought, given the dynamic of people who carry weapons, that we were maybe in Texas," he says. "But in fact, we were in Detroit, Michigan!"

If you're murdered in America, there's a 1 in 3 chance that the police won't identify your killer.

To use the FBI's terminology, the national "clearance rate" for homicide today is 64.1 percent. Fifty years ago, it was more than 90 percent.

And that's worse than it sounds, because "clearance" doesn't equal conviction: It's just the term that police use to describe cases that end with an arrest, or in which a culprit is otherwise identified without the possibility of arrest — if the suspect has died, for example.
